An immigrant visa is a type of visa that allows foreign nationals to live and work permanently in a new country. These visas are typically granted based on family relationships, employment opportunities, or humanitarian reasons. Applicants must meet specific eligibility criteria and go through a detailed application process. Once approved, an immigrant visa enables individuals to enter the country as permanent residents. This status often leads to the ability to apply for citizenship after fulfilling certain residency requirements. Immigrant visas are essential for those seeking a long-term future in a new nation.
